A National Public Radio poll of likely voters, conducted by Democrat Stan Greenberg of Democracy Corps and Republican Whit Ayres of Resurgent Republic, shows that 46 percent of likely voters approve of the president; 51 percent disapprove.

That is slightly less than Obamacare approval numbers which show that 47 percent support and 51 percent oppose. Those numbers are up.

"The conventional wisdom that it's an unpopular program that hangs around the necks of Democrats is absolutely a misreading of the poll data," Greeberg said in the NPR report.

But, the polls also show that the number of people who intensely oppose the law is 12 points higher than those who strongly support it.

"First, more people oppose than support Obamacare, as has been the case since it passed," Ayres, the Republican, said in the NPR report. "Second, the intensity is on the side of the opposition, and intensity drives voting behavior."

Greenberg points out that 7 percent oppose the law because it doesn't go far enough -- those who may have wanted a single-payer system.
